Air pollution sensor, control and monitor air quality | Airly

Sensors measure the particulates using the laser method. In the case of gas pollutants, our single device is able to measure two chemical compounds by electro-chemical method. Readings are taken from two cells installed in the gas module of the sensor. Each sensor has a special light diode that changes to clearly show the current air quality using a colour consistent with the CAQI scale.
